Zeus sat cross-legged on the ground, his body trembling as waves of intense pain coursed through him. The thunder mana that the system had absorbed and funneled into the Zeus Divine Mask was now swirling within him, raw and potent, like a storm waiting to be unleashed.
His task now was to condense this mana, to forge it into a form that would strengthen the temporary Heavenly Thunder Core within the mask.
Every muscle in his body screamed in agony, his bones felt as though they were being ground to dust, and his veins burned as if molten lightning coursed through them. But Zeus knew that this pain was necessary. He had to endure it if he wanted to break through and reach the next level.
